OmicSnap.
A defined amount, never a guess.
OmicSnap collects a fixed, defined mass of stool, 100 mg by the maker’s figure, into a prefilled tube that stabilises and homogenises it for nucleic-acid work: a standardised input for reproducible, quantitative microbiome analysis, without the variable scoop, collected by the patient at home or by a professional. CE marked. Curated and supplied on the Humans Nexus platform; Immundiagnostik is the manufacturer.
Volumetric stool,
standardised.
OmicSnap, the OmicSnap® NATcp system, is an all-in-one device for the manual collection of a defined amount of stool, 100 mg, into a prefilled tube that stabilises and homogenises the sample for nucleic-acid-based procedures in the laboratory. Because the collected mass is fixed rather than estimated, the input to sequencing is standardised from patient to patient. Humans Nexus curates and supplies the device on its platform and assembles the regulated kit around it; Immundiagnostik is the legal manufacturer.
In the maker’s words, OmicSnap is an all-in-one system for the manual collection of a defined amount of stool by professionals and laypersons, 100 mg, that allows stabilisation and homogenisation of the sample for nucleic-acid-based procedures in the laboratory, and it is CE marked.
The scoop is the variable.
Classic stool collection takes an unmeasured scoop, so the amount of material entering the buffer varies from sample to sample, and a variable input undermines quantitative and comparative microbiome work. OmicSnap fixes the collected mass by design, the same way a volumetric blood device fixes the collected volume: standardise the input, and the downstream sequencing becomes reproducible and comparable across patients and across time.
What the record shows. Faecal microbial load varies up to tenfold between healthy people, so relative profiling can misread the direction of change; quantitative profiling needs counts, which start with a defined input (Nature, 2017). In a systematic study of sampling and storage, homogenised, snap-frozen stool was the reference against which storage conditions were shown to shift both microbiome and metabolome (mSphere, 2020). And a NIST-led workshop set out the case for a characterised whole-stool reference material, because measurements cannot be compared across laboratories without a standard input (Metabolomics, 2020).
Dose. Stabilise. Return.
The device collects a defined amount of stool: guided, hygienic, and the same measured mass each time.
The sample drops into the prefilled tube, which stabilises and homogenises it for nucleic-acid analysis.
Cap the tube and drop it in the tracked mailer, chain of custody from the first second.
Assembled into a kit.
OmicSnap is curated onto the platform and assembled into a regulated Humans Nexus collection kit: device, prefilled stabiliser tube, tamper-evident return packaging and app-guided instructions, under its own UDI.
For quantitative gut work.
Good to know.
What makes OmicSnap different from a standard stool collector?
It collects a defined, fixed amount of stool rather than an unmeasured scoop. That standardised input is what makes microbiome results reproducible and comparable across patients and over time.
How much stool does OmicSnap collect?
100 mg, per the maker: a defined amount into a prefilled tube, the same each time.
Why does a defined mass matter?
Because faecal microbial load varies up to tenfold between healthy people. Counts per gram need a known input, and a variable scoop makes relative abundances hard to compare across samples and over time.
What does it collect for?
The prefilled tube stabilises and homogenises the sample for nucleic-acid-based procedures, microbiome sequencing and related metagenomic work, in the laboratory.
Who can collect with it?
Professionals and laypersons, per the maker: the patient at home, guided step by step, or a clinician at the point of care.
Who is the manufacturer?
Immundiagnostik makes the OmicSnap device. Humans Nexus curates and supplies it on the platform and assembles the regulated kit around it. Method validation runs per assay before patient-facing reporting.
What is its regulatory status?
OmicSnap is CE-marked per the manufacturer. Device-level regulatory status is held by Immundiagnostik; Humans Nexus assembles the regulated kit around it.
